The rendering system change didn't do much, sadly. I removed a couple of mods I had downloaded earlier and at least I can see inside text boxes now.
I tried to create a new character, didn't like it. Got stuck on the 'creating' screen again.
Also attempted to make a new character without touching the original base one, then went back in to edit it and tried to save it. Stuck on the 'updating' screen.
Edit; From what I've found while playing around, if I take around 5 or more minutes to make a character, it doesn't like it. But if I modify a little part, then save, modify a little part, then save, it's fine with it. Not sure if it could have anything to do with a connection issue or not, it's just a pain. I'll survive like this for now but if anyone has a fix of some sort at all I will be extremely grateful.
Edit 2; It seems to be a name issue now? If I slap my keyboard and just name it 'gfdgdfgfd' it'll be cool, but I want to call my character 'Mocha'. If I change it's name to that, it hates me.
Edit 3; Lord have mercy, either this game or my computer, lmao... Anyway I kept changing the name to random things until it decided to accept 'Mocha' as the name. Pretty odd that all of this is happening, but I finally got there, ahaha.
